From newborn calves to long-standing family groups, Norway’s killer whales are navigating a rapidly changing ocean. By following individuals and families through time, we track their lives, health, and behaviour to understand what they need to survive—and how best to protect them. Norwegian Orca Survey has built one of the longest continuous killer whale datasets in the world, and the very first systematic stranding sampling program in Norway. This long-term science directly informs national and international conservation policy. Every contribution helps turn observations into knowledge, and knowledge into potential for future action for killer whales and the oceans they depend on.
